Question

Which of the following equations would have the solution of n=22 ?(1 point)
Responses

3n−28=38−14
3 n minus 28 equals 38 minus 14

n+16=38−15
n plus 16 equals 38 minus 15

n−15=7+15
n minus 15 equals 7 plus 15

n+16=18+20

Answer 5

n+16=38−15 is the equation that would have the solution of n=22.

Answer 6

x = 7 is the solution that would make the equation 36 - 22 = 2x true.

Answer 7

Using substitution, the number 25 from the set {15, 25, 35, 55} makes the equation y + 15 = 40 true.

Answer 8

Using substitution, the number 13 from the set {6, 13, 18, 26} makes the equation 2x + 5 = 31 true.

Answer 9

Using substitution, the correct number from the guesses {6, 12, 13, 36} is 12.
